The saw clamp comprises aback jaw 10 Which consists of a vertically-extending plate 10a and a transverse plate 10b extending rear- Wardly therefrom below the upper edge thereof. The plate 10b is adapted to rest upon a supporting member 11 and is provided adj acent each end, and at other points, if desired, With downwardly extending spurs or spikes 12, Which are adapted to be driven into the member 11 to hold the jaw' of the clamp securely in position.V A number of holes 11a are also provided in the in'g deyic'e for 5 holding' 'the s'aW*-firml`y din'- ingthe l`Operations of fillnggifsetting, or-reil Vertical depth adjacienty theffcentnerlof'the clamptoforni downivardlyfiextendiifgfporf vproximity to the underfs'idfes; ofthellflanlge :'i

coa'ct :With aA saw placedi hetwezenfitheniff The Spacing Vblocks /13'l are*ofg''slightly'fgreater thickness than'fthe 'mf-:tall of the*zspring. Vso i that the arm 17b is permitted to'lturnifreelyi the spring in one direction, but'the curved portions 20 permitthe spring to be folded*` npwardly into the position shown in Fig. 2. In order to prevent the 'onter jaw 15 from swinging on its pivot, it is provided'at the end opposite the curved portion 20'of the spring With ay Weight 22 Which holds that end of the onter jaW doWnWardly With the underside of the rib in contact with the square portion 21 of the s ring. The Vrear jaW is, of course, held in Xed lposition by reason of itsV connection With the supporting member 11. The parts of the clamp are thus held in the proper relation'to each other by no means of the connecting spring alone Which A is pivotally attached to them, and the resilient spring permits these javvs to be separated tov receive the blade of a saw 23 ,betWeen them. In order to prevent vibration and chattering of the saW When it is beinof filed or otherwiseworked upon, a strip oI felt, or the like, 25 is placed along` tlie inner side of the Outer jaW in contact With the face of the plate 15a, and the ends of this strip of felt are inserted into apertures 26 Which are formed in the'opposite ends of the rib 15h, Plugs 27 are driven into these apertures to 'hold the felt securely in contact With the face of thevjaw,

It Will be apparent that the clamp coniprises a minimum number of parts Which are united 'in a practical and simple manner, so that the saw blade 23 is securely held under spring tension. The construction of the clamp permits the saw to be readily inserted orivithdrawn from its position between the JaWs, and the. construction of the .cl-amp andv the method of inounting,` the same permitit to be conveniently carried about and reaidily mounted in any desired position.

Although rIvl have shown and described a single embodiment of the invention foi' purposes of illustration, it Will be understood that itfmay be constructed in various other forms Without departing froin the scope of the appended claims. f

yVtfhat Igclaim is:

1'. In combination, a jaW having means foi' eiigagingla support, a movable jaw monnted parallel to said first-named javv, spring actuated means for connecting and normally holding said jaivs in san7 engaging relation, a strip of deadening material located along the-inner surface of one of said jaws, and

removable means for securing said deadening material to the ends of the jaw by Which it is carried.

2.111 combination, a jaw having means for engaging a support, a inovable jaW mounted parallel to said first-named jaW, spring actuated means for connecting and actuating said jaws, a strip of deadening material located along the inner surface of one of said jaivs, one of said javvs having apertures in the ends thereof adapted to receive the ends of said strip, and plugs engaging said apertures to secure .said strip in position.

ln combination, a fixed jaiv, a movable jaW, a loopcd spring having the end poi'tions thereof pivotally connected to said jaws, each end poi'tion of said spring having a flat end surface with a rounded corner to permit folding` of said spring in one direction, means carried by said jaivs to engage the flat end surface of said spring, and a counter-Weight carried'by said movable jaw oii the end Vthereof opposite the rounded corners of said spring.

4-. ln combination, a jaW comprising a horizontal i'flange adapted to rest on a support and a vertical plate adapted to lie alongside the `vertical face of said support. means foi' spacing said plate outivardly from said support, a movable jaw extending alongside said first-named jaiv, and a resilient connecting` member having` its end portions extending on opposite Sides of and pvotall)`v connected to said jaivs, one end portion of said spring lying between said vertical plate and the vertical face of said support.

lrn combination, a comprising a horizontal flaiige adapted to rest .on a support and a vertical plate adapted to lie along'side the vertical face of said support, means for spacing said plate outwardly from said` support, a movable aiv extending alongside said first-named jaW, and a resilient connecting` member having its end portions cxtcnding on opposite sides of and pivotally connected to said jaWs, one end portion of said spring lyingbetween said vertical. plate and the vertical face of Vsaid support, said movable jaw having a longitudinal rib on its outer side along` its upper edge, the end portions of said connecting ineinber having fiat end surfaces adapted to engage said horizontal iiange and said rib, one corner of each end of said connecting` member being i'ounded to pei'init folding thereof.
